2 Claims.

'I'his invention relates to heddle frames for looms, and it relates more particularly to the construction and arrangement of such heddle frames.

Heretofore, in that type of heddle frame which has been most commonly used for mounting merods, whereby the intermediate portions of. the end members are left clear and unobstructed over .outer faces to permit (Cl. 139-91) l v scri tra ption and drawing herein contained are illustive merely, and that various modifications Referring to the drawing, in the particular embodiment of the invention therein shown,

bent over and extending thereof, as at I2. These bent over portions I2 are secured to the rails I0 by wood screws I 3. Corner braces I4, of the type Shown in my previous Letters Patent No. 980,285, may be employed rails, being secured thereto by wood screws I5.

The heddle supporting rods I 6 are of the usual type, having their end portions extending through suitable slots in the end members I I. Those portions of each heddle supporting rod which extend apertures I 7, members to be hereinafter described.

Any preferred means for supporting the heddle rods I6 intermediate their ends may be employed.

an auxiliary rod I8, supported at suitable intervals by screw eyes I9 mounted in tion of the rail ID, and having slide hooks 20 end faces of each rail I0, two apertures 2|, through which portions of the heddle rod retaining member extend.

From the outermost aperture 2|, the end portion 22 of the retaining member extends along the outer face of the end member I I.

aperture I1 in the extending end portion heddle supporting rod I6, which aperture is provided for that purpose.

The end portion of each rail l0 is recessed, as

at 26, to permit the portion 23 of the retaining member, which extends along the inner face of the end member Il, to be seated in said recess, so that there will be no interference with the proper mounting of the end member Il on the end portion of the rail I0.

The present invention is particularly useful in connection with that type of frame in which duplex heddles are mounted. These frames are sometimes provided with wires 21 which extend longitudinally in the frame between the two sets of heddles 2B, serving to prevent fouling of said heddles on each other. As shown, each end of each of these wires 21 'is provided with a loop 29 extending through a suitable aperture in the end member Il, which loop may be engaged by a spring retaining hook 30. The retaining hook 30 may be secured by means of a rivet 3l, mounted in the end member Il, as clearly illustrated in the drawing.

It will be noted that, by the arrangement of the heddle rod retaining devices as hereinbefore set forth, the intermediate portion of each end member Il, between the heddle supporting rods IB, is left free of said retaining members, so that the devices for securing the wires 21, or other devices of like character but used for dierent purposes, may be provided. Where such devices are not used, the end members Il are left free of obstructions on their outer faces between the heddle supporting rods I6, so that they may be engaged by guide members (not shown) to prevent side sway of the frames, which is frequently desirable. Even in the form shown, where the separator wires 21 are employed, there is still sufficient length of the end members Il left unobstructed to permit such guide members to be employed if desired.

A heddle frame constructed in accordance with the present invention will also be found to be more rigid, in that a considerable length of the intermediate portion of each end member is left free of apertures which weaken the same.

I claim:

l. A heddle frame comprising top and bottom rails, end members made of flat strips of metal having portions extending across the end faces of said top and bottom rails, heddle supporting rods having their end portions extending through the end members, and spring wire retaining members mounted in the end members for securing the heddle supporting rods, said retaining members being secured to said end members in the portions thereof which extend across the end faces of the rails, each of said retaining members having a portion extending along the inner face of the end member, and a portion extending inwardly which engages an aperture in the end of the heddle supporting rod, the end portion of the rail having a recess in which is disposed that portion of the retaining member' which extends along the inner face of the end member.

2. A heddle frame comprising top and bottom rails, end members made of flat strips of metal having portions extending across the end faces of said top and bottom rails, heddle supporting rods having their end portions extending through the end members, and spring wire retaining members mounted in the end members for securing the heddle supporting rods, said end members having apertures in the portions thereof which extend across the end faces of the rails through which apertures portions of the retaining members extend, each of said retaining members also having a portion extending along the outer face of the end member, a portion extending along the inner face of the end member, and a portion extending inwardly having a hook-like terminal which engages an aperture in the end of the heddle supporting rod, the end portion of the rail having a recess in which is disposed that portion of the retaining member which extends along the inner face of the end member.
